#mkboot /dev/rdsk/cXtXdX
d.
Use the
mkboot
command again to add the HP-UX auto-file-string. For example:
#mkboot -a "hpux" /dev/rdsk/cXtXdX
e.
Run
lvlnboot
. For example:
#lvlnboot -R
f.
lvextend
a mirror into the replaced disk drive. This may take several minutes because this
function copies all the data from the original copy of the data to the mirrored extents. The
logical volume(s) are still accessible for users' applications during operation of this command.
#lvextend -m 1 <LV name> /dev/dsk/cXtXdX
For example:
#lvextend -m 1 /dev/vg00/lvol4/dev/dsk/cXtXdX
#lvextend -m 1 /dev/vg00/lvol5/dev/dsk/cXtXdX
Repeat this procedure for each logical volume to be mirrored
Step 3.
Verify that the mirror is bootable and AUTO file is correct.
#lifls -l /dev/rdsk/cXtXdX
#lifcp /dev/rdsk/cXtXdX:AUTO -
Step 4.
Verify that the mirroring is set up properly.
#vgdisplay -v /dev/vg00
#lvdisplay /dev/vg00/lol1 - lvol8
#lvlnboot -v /dev/vg00
Both disks should list as "Boot Disk" and both should appear in the
lvol
lists.
At this point, the system is fully functional.
HP-UX HotPlug Procedure for Unattached Physical Volumes
Follow these steps to replace a HotPlug disk drive for unattached physical volumes.
NOTE
HP often uses different manufacturers for disks having the same product number. The HotPlug
manual procedure will not update the disk drivers internal information to that of the replaced
disk drive.
Step 1.
Perform an
ioscan
on the replaced disk drive to ensure that it is accessible (claimed) to verify that it
is a proper replacement and the device files are present. Refer to the above note. For example:
# ioscan -fnC disk
Step 2.
Restore the LVM configuration/headers onto the replaced disk drive from your backup of the LVM
configuration:
#vgcfgrestore -n <volume group name> /dev/rdsk/cXtXdX
